The present invention is a continuation-in-part of U.S. patent application Ser. No. 12/938,607, filed 3 Nov. 2010, pending and to be abandoned.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a protective sheath device, and more particularly to a protective sheath device including an improved structure or configuration or mechanism for solidly and stably and firmly anchoring or retaining the blades of the kitchen cutlery, kitchen tools and various other implements within the sheaths and for allowing the blade to be easily and quickly removed from the sheath by the user.

2. Description of the Prior Art

Various kinds of typical protective sheath devices have been developed and provided for receiving or engaging with or for storing blades of kitchen cutlery, kitchen tools and various other implements, and comprise various structurally independent mechanisms for securing blades within the sheaths, such as straps, clips and clamps.

For example, U.S. Patent Application No. 2011/0139645 to Ranieri et al. discloses one of the typical protective sheath for storing blades of kitchen cutlery, kitchen tools and various other implements, and also comprises an enclosed chamber or cavity formed therein for receiving or engaging with the blade of the kitchen cutlery, kitchen tools and various other implements to be sheathed and protected.

However, one disadvantage of the protective sheath is that the chamber or cavity or compartment formed or provided in the protective sheath is an enclosed space that the water contained in the protective sheath may not be easily flown out or drained out of the protective sheath.

In addition, the anchoring or retaining or securing structures or configurations or mechanisms, such as straps, clips and clamps formed or provided in the protective sheath may be used for securing blades within the sheaths with a gripping or clamping force.

However, another disadvantage of the protective sheath is that the blades are solidly and stably and firmly received or engaged or anchored or retained within the sheaths with the gripping or clamping forces and may not be easily and quickly removed from the sheaths, and the users have to use both their hands to remove the blades from the sheaths.

U.S. Pat. No. 4,714,159 to Linden discloses another typical protective sheath or package for storing blades or scissors and comprising an enclosed chamber or cavity formed in a casing for receiving or engaging with the blade of the kitchen cutlery or scissors to be sheathed and protected.

However, the disadvantage of the protective sheath or package is that the blades also may not be easily and quickly removed from the sheaths, and the users have to use both their hands to remove the blades from the sheaths.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional protective sheath devices for storing blades of kitchen cutlery, kitchen tools and various other implements.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a protective sheath device including an improved structure or configuration or mechanism for solidly and stably and firmly anchoring or retaining the blades of the kitchen cutlery, kitchen tools and various other implements within the sheaths and for allowing the blade to be easily and quickly removed from the sheath by the user.
